[0002] A type of four-part lower frame right mounting foot (see) Figure 4 After production, the holes and cut edges of the product need to be inspected to ensure compliance with requirements. Since this product involves the inspection of multiple surfaces and holes, its main surface consists of planes and curved surfaces, with side elevations formed after stamping and trimming. The front half of the product includes main holes and secondary holes, while the two side elevations in the rear half contain shaft holes I and II, respectively. Shaft holes I and II need to be coaxial. Manually inspecting each hole individually would be time-consuming, difficult, and inaccurate. Therefore, a specialized inspection tool for this part is needed to improve inspection efficiency and accuracy. Thus, there is an urgent need to develop an inspection tool for the right mounting foot of this four-part lower frame to achieve quick and convenient positioning and improve inspection efficiency and accuracy.

[0005] A further technical solution of this utility model is: a go / no-go gauge with a diameter of 2.5 to 3.5 is provided on the front part of the chassis.
[0006] A further technical solution of this utility model is: a flush gauge is provided on the left side of the chassis, and the tolerance of the flush gauge is ±0.5mm.
[0007] A further technical solution of this utility model is: a coaxial pin is provided on the middle part of the chassis.
[0008] The beneficial effects of this utility model are as follows: by adopting the above technical solution, the four-part lower frame right mounting foot inspection tool of this utility model can quickly and accurately position, fix and inspect the four-part lower frame right mounting foot, which can effectively improve the accuracy and efficiency of the inspection.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0015] Example:
[0016] like Figure 4 The illustrated four-part lower frame right mounting foot 4 includes a main surface 40, which is composed of a plane and a curved surface. The two sides of the main surface are side elevations 45, which are formed after stamping and trimming. The front half of the product includes a main hole 41 and a secondary hole 42, and the two side elevations of the rear half also have shaft hole I 43 and shaft hole II 44 respectively.
[0017] like Figure 1 , 2 A four-part lower frame right mounting foot inspection fixture, as shown in Figures 3 and 5, includes a chassis, a main seat 7 mounted on the chassis, and a positioning block 6 mounted on the top surface of the main seat. The surface formed on the top surface of the main seat after the positioning block is installed is adapted to the shape of the main surface of the four-part lower frame right mounting foot. The positioning block is set as a reference surface. The positioning block is also provided with a main positioning pin hole and a secondary positioning pin hole. The main positioning pin hole and the secondary positioning pin hole are respectively configured with a main positioning pin 1 and a secondary positioning pin 2. A quick clamp 8 is provided on the left side of the main seat. The quick clamp includes a chuck 81. When the quick clamp is in a non-tooling state, the chuck flips upward and rises. When the quick clamp is in a tooling state, the chuck flips downward and presses down. Detection pins 3 are respectively provided on both sides of the rear half of the main seat.
[0018] Further, a go-no-go gauge 9 with a size range from 2.5 to 3.5 is provided on the front part of the chassis. During inspection, if it passes through the 2.5 mm hole, it is considered qualified; otherwise, it is unqualified.
[0019] Further, a flush gauge 10 is provided on the left part of the chassis, with a tolerance of ±0.5 mm. The flush gauge can be used to detect the corresponding trimmed surface of the product.
[0020] Further, a coaxial pin 5 is provided in the middle part of the chassis. The coaxial pin can be used to detect whether the shaft hole I 43 and the shaft hole II 44 are coaxial.
[0021] When using the inspection fixture, open the quick clamp 8 to make it in a non-working state. Take the positioning block 6 as the reference surface of the product, place the product in, then close the quick clamp 8. Insert the main positioning pin 1 for main positioning and insert the secondary positioning pin 2 for secondary positioning to position the product. Use the inspection pin 3 and the coaxial pin 5 to detect the corresponding hole positions. If it passes smoothly, it is qualified. Use the go-no-go gauge 9 with a size range from 2.5 to 3.5 to detect the clearance of the corresponding peripheral surface. If it passes through the 2.5 mm hole, it is qualified; otherwise, it is unqualified. Use the flush gauge 10 with a tolerance of ±0.5 mm to detect the corresponding trimmed surface. If the clearance is between ±0.5 mm, it is qualified. During the process of placing the part, do not forcefully press the product and the pins. Observe whether there is any scratching at other positions.
[0022] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
